Due to the recent surge in interest in multirotor aircraft we have recently added the EMax BLHeli ESC range to our catalogue. These ESCs have been designed and optimised for multirotor applications. They represent a massive step forward in off-the-shelf ESC design.

The BLHeli range uses a SiLabs processor running BLHeli firmware upgraded to incorporate several improvements and additional features such as higher update rates which give much quicker linear throttle response when compared to regular non-multirotor ESCs.

EMax is now a member of the BLHeli team of developers and contributors and the first ESC manufacturer to publish source programming in China.

Features
* Authentic electronic components to ensure high quality and enhance the electrical current endurance ability of the ESC
* Based on BLHeli firmware, optimised for high performance with great linearity and much quicker throttle response
* Specially designed for multirotors but also compatible with fixed-wing aircraft and helicopters
* Rotation direction of the motor is programmable: normal, reverse or bi-directional
* Multiple programmable protection features including: low-voltage cut-off protection / over-heat protection / throttle signal loss protection
* Integrated lost model alarm – after a short delay the ESC will beep when the throttle is moved to the fully closed position
* Throttle range can be configured and is fully compatible with all receivers, providing smooth, linear and precise throttle response
* All parameters can be programmed using a program card or directly from your transmitter

Standard BLDC 30 amp ESC Electronic Speed Controller with Connector is specifically made for quadcopters and multi-rotors. It provides faster and better motor speed control giving better flight performance compared to other available ESCs.

STANDARD 30 amp ESC Electronic Speed Controller can drive motors that consume up to 30A current. It works on 2-3S LiPo batteries. The onboard BEC provides regulated 5V(2A max draw) to power the flight controller and other onboard modules. This is useful to control our brushless motors with a 2-3S LiPo battery (make sure the motor doesn’t draw more than 30A).

This particular ESC is recommended with an A2212 brushless motor (1000kv, 1400kv, 2200kv).

ESC CONNECTORS:
  • Battery Side – Male Deans ( T ) Connector.
  • Motor Side – Female 3.5mm Gold Connector.

Features:

  1. This 30 amp ESC for BLDC has onboard BEC
  2. This ESC comes with a male dean T-connector
  3. Auto Low BATTERY Slow down at 3.0V/cell Lipo, cut-off at 2.9V/cell lipo
  4. APPLICATION: Multirotors, Rc Airplanes, etc

Package Includes:

1 x Standard 30A BLDC ESC Electronic Speed Controller with Connectors
